UNITED STATES FATENT @FFTQFQ WILSON E. PORTER, OF NEW HAVEN,CONNECTICUT, ASSIGNOR TO NEW HAVEN CLOCK (30., OF NEW HAVEN,CONNECTICUT, A CORPORATION.

CLOCK-MOVEMENT.

To all whom it may concern:

Be it known that I, VVILsoN E. PORTER, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement inClock-Movements; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1 a view partly in side elevation and partly in section of aclock-movement constructed in accordance with my invention. Fig. 2 adetached view thereof in rear elevation. Fig. 3 a detached perspectiveview of one of the pillars. Fig. 4C a perspective view of one of thepillar-sleeves.

My invention relates to an improvement in clocl:n1-ovenients andparticularly to that class of clock-movements having intermediatemovement-plates and therefore requiring the employment of specialpillars, such, for instance, as clock-movements in which thewinding-arbor and center-arbor are located in line with each other, andwhich therefore require one or two intermediate movementplates inaddition to the ordinary front and rear movement-plates.

The object of my invention is not only to simplify the construction ofall such clockmovements, but also to facilitate the assemblance anddismounting of their parts, and to secure for them greater accuracy oflining up.

With these ends in view my invent-ion consists in a clock-movementhaving certain details of construction as will be hereinafter describedand pointed out in the claims.

For the purpose of illustration and description, I have chosen to applymy invention to a clock-movement having a front movement-plate 2, a rearmovement-plate 3, and front and rear intermediate movementplates 4: and5. The center arbor 6 has bearing at its forward end in the frontmovement-plate 2, and at its rear end in the front intermediate plate 4,while the forward end of the winding-arbor 7 has bearing in the rearintermediate plate 5 and in the rear movement-plate 3. Under thisconstruction the center-arbor 6 and the winding-arbor 7 are located inline, the rear end of the center- Speeification of Letters Patent.

arbor and the forward end of the windingarbor coming close together. Nowthe employment of the two intermediate movement plates 4: and 5 makes itnecessary to organize them with the ordinary front and rearmovement-plates 2 and 3. For this purpose I employ long pillars 8 eachformed at one end with a screw-hole 9, and at the opposite end with arivet 10, and each being adapted in length to connect the front and rearmovement-plates 2 and 3, though made short enough to provide the take-upspace 11 produced by failing to extend their rear ends clear through therear plate 3. As shown there are four of these pillars, but the numbermay be varied as desired.

The rivets 10 of the pillars 8 are passed forward through rivet-holes 12in the front plate 2 and swaged down thereupon, whereby the front-plate2 is secured to all of the pillars. For the purpose of spacing theplates 3, 4 and 5 upon the pillars, I employ spaoingsleeves 13 and 1aand spacing-collars 15, all just enough larger in diameter than thepillars 8 to slip over the same and gaged in length by the spaces whichit is desired to establish between the respective plates 2, 3, 4 and 5.Thus, the spacing sleeves 13 are made just long enough to establish aright distance between the plates 2 and t. So, too, the spacing-collars15 are made just wide enough to establish a sufficient clearance-space16 between the intermediate plates 4: and 5. The sleeves 1a are madelong enough to establish the required space between the plates 3 and 5.These spacingsleeves and collars will, of course, be varied in lengthaccording to the particular requirements of each movement.

In assembling the parts of my improved movement, the rear movement-plate3 is left to the last, it being placed over the rear ends of the pillars8 so as to rest upon the rear ends of the spacing-sleeves 1-1. Thepillar screws 17 are then entered into the screw holes 9 in the rearends of the pillars and turned home, whereby all lost motion between theplates and sleeves and collars is taken up in the take-up spaces 11. Thepillars 8, spacing-sleeves 13 and 1a and the spacing-collars 15 may bevery accurately produced at a low cost, and effect a far more accuratelining up of the clock-movement than do sectional pillars adapted tohave their sections screwed into each other.

1 have shown and described my invention as applied to a movement havingfour plates, on account of its peculiar applicability thereto, but it isapparent that it may he used in the construction of movements hav ingonly three plates. l Vhet-her applied to clock-movements having three ormore plates, my improved pillars with their spacingsleeves andspacing-collars invariably secure the correct predetermined distancesbetween the plates, since even if the riveting of the pillars tends tobreak down or deform their shoulders, this will be corrected by the spacing-sleeves when the same are applied as they are invariably of the samelength and not subject to any hammering or deformation in assembling themovement.

I am aware, however, that it was old prior to my invention to employspacing-sleeves for spacing the movement-plates of clocks employing morethan two movement-plates, and do not therefore claim. such aconstruction broadly.

I claim 1. In a clock-movement, the combination with a center-arbor anda winding-arbor located in line with each other, of front and rearmovement-plates respectively providing a bearing for the forward end ofthe center-arbor, and for the rear end of the winding-arbor, twointermediate movementplates respectively providing a bearing for therear end of the center-arbor and the forward end of the winding-arbor,pillars connecting the said front and rear plates, spacing-sleevesmounted upon the said pillars and respectively interposed between thesaid front and rear plates and the said intermediate plates, and spacingcollars interposed between the said intermediate plates which have but anarrow clearance space between them.

2. In a clock-movement, the combination with the front and rearmovement-plates thereof, of pillars formed at their forward ends withrivets entering rivet-holes in the front inovementplate and swaged downthereupon, and having their rear ends ontered into holes in the rearmovement-plate and formed with screw-holes, pillar-screws passed throughthe rear movement-plate into the said screw-holes in the pillars, one ormore intermediate plates located between the front and rearmovement-plates, and spacing sleeves mounted upon the said pillars andinterposed between the several movement-plates, take-up spaces beingformed in the said rear movement-plate by proportioning the pillars inlength to the length of the said sleeves.

In a clock-movement, the combination with a center-arbor and awinding-arbor located in line with each other, of circular front andrear movementplates respectively providing a bearing for the forward endof the center-arbor and for the rear end of the winding-arbor, twocircular intermediate movement-plates respectively providing a bearingfor the rear end of the center-arbor and the forward end of thewinding-arbor, the said center and winding arbors being located in thecenters of the said front, rear and intermediate plates, pillarsconnecting the said front and rear plates and passing through the saidintermediate plates, spacing sleeves mounted upon the pillars andrespectively interposed between the inner faces of the front and rearplates and the outer faces of the intermediate plates, spacing collarsmounted upon the said pillars and interposed between the saidintermediate plates which are separated by a narrow clearance space, andmeans for securing the pillars at their ends to the front and rearmovementplates.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses;
